“…To take into account the time correction of the synchronization of the satellite's atomic clock and the one of the ground control station, we use the following formula [20]: We choose the following notation: the coordinates are taken in square brackets, in them the reference frame is denoted in parentheses, the superscript indicates the type of the coordinate. For example, a = 0 corresponds to time coordinate ct; a = 1, 2, 3 corresponds to spatial coordinates in the cylindrical coordinate system, R is cylindrical radius, φ is cylindrical longitude, z is axis cylindrical coordinate system respectively; g(8)00, g (8)0α are the components of the metric tensor in the geocentric reference frame {х(8) α } (the four-dimensional metric tensor will be denoted by g; the subscripts indicate a specific component of the tensor, the reference frame for which the given tensor is found is indicated in parentheses, the frames of reference will be taken in curly brackets.…”
